I dont know where to ask but seem to be issue with Firefox and firefox only and only on dad surface. Example none of PNC account work for him in Firefox on surface, IF i use my pnc account which works fine on my pc and using same version of firefox that is on his surface i can log in fine, IF i try mine on his surface it fails. IF I try same info on edge on surface is works fine. I have already Tried new profile on firefox on the surface and even that fails to login. refresh of profile fixes nothing. The only addon on his surface is ublock origin which is using the SAME filter i use on my pc. But what no sense to me is that all the passwords that wont work in in firefox even a new profile work fine threw edge as far as i can tell. And this not first time he complained about password not working in firefox, i have no clue what he did or happen cause i have zero issue with my passwords in firefox. only thing i can think of something change with defender to cause this but was working, I did CU update other day on surface but it was not related to defender and same CU my pc has too and i have no issue Removing this update which was preview https://nationalcybersecuritynews.t...wo-new-features-firefox-chrome-microsoftedge/ Did not fix the issue with firefox on his surface. I am now at lost as to why none password will work on the surface but will work on my pc and will work edge on surface Niether did switching from Defender to Avast. It just wont let me login to pnc on the surface with firefox, and i not about reinstall windows for test, seeing completely uninstalling firefox and creating new profile fixes nothing.
